Title: Power supply device
Inventor: KOUSAI YOSHIHARU
IPC: H02J7/00
Filed: 1990-11-21
Abstract: PURPOSE:To eliminate wasteful charge or wastefulness with storage battery by sampling the battery voltage at the time of discharging at certain intervals, and comparing the voltage values, and thereupon sensing the memory effect of the battery. CONSTITUTION:A voltage signal of a Ni-Cd battery 8 is entered into a microcomputer 7 at regular intervals from an A/D converter 6. As the voltage of a storage battery falls steeply at a point near the final value of battery voltage, the microcomputer 7 determines the voltage damping amount -DELTAV per unitary time to know the discharge ending time of the battery 8. In some cases according to the operating condition of the body 5 of a device concerned, however, the voltage may fall in the form of spike, and therefore the mean of the sensing data for several runs is used as battery voltage. Because a two-step fall of battery voltage is generated in a battery 8 in which the memory effect has appeared, the microcomputer 7 senses a two-step fall of voltage from the voltage damping amount -DELTAV, lights up an LED 11 through a switching transistor 13, and informs the user that the memory effect has appeared in the battery 8.

Title: Planar semiconductor device
Inventor: ENDO KATSUHIRO
IPC: H01L29/744
Filed: 1993-12-17
Abstract: PURPOSE:To obtain the planar semiconductor device in which the stress from an external pressurization mechanism of a semiconductor substrate is dispersed so as to become uniform and which is stabilized mechanically and in terms of a characteristic by a method wherein the outside diameters of both a cathode electrode body and an anode electrode body are made nearly identical at the inside and the outside of a container and the direction of the stress due to pressurization in the vertical direction with reference to electrode faces from the external pressurization mechanism is reduced. CONSTITUTION:The outside diameters of both a cathode electrode body 32 and an anode electrode body 31 are made nearly identical in such a way that the diameter PHI5 at the inside of a container is 79mm and that the diameter PHI4 at the outside is 80mm. In addition the diameter PHI3 of 12mm of a recessed part 32a in the center of the cathode electrode body is made partly large, and a cutout part 32b in a diameter PHI6 of 13mm is formed. When the diametersof the electrode bodies are made nearly identical at the inside and the outside of the container, the deviation of a stress to an electrode-face peripheral edge part 32d due to a pressure from an external pressurization mechanism can be reduced. In addition, since the cutout part 32b is formed, a stress which is concentrated near a recessed part 32e in the cathode electrode body can be relaxed by a contact electrode plate. As a result, a pressure to which a semiconductor substrate is subjected is made uniform, and the dange of its destruction can be reduced.
